Anna Ohura (大浦あんな, Ōura Anna?) (born May 30, 1980) is a Japanese AV (adult video) performer and model, known for her very large (100-centimeter, metric I-cup) natural breasts. In 2003, according to the Taipei Times, she claimed to have the largest breasts in the Japanese adult film industry.

Anna Ohura was born in Hokkaidō,to a French father and Japanese mother. She says that most people think she resembles her father. She says that her grandmother is the person she most respects.

Ohura is left-handed and has poor eyesight, usually wearing contact lenses. She enjoys drinking and smokes occasionally. She likes udon noodles, but dislikes soba noodles. Ohura's favorite subjects in school were social studies and Japanese, while English and mathematics were her worst. As a child, she wished to become a comic book writer, and she has commented that if she had not gone into the adult entertainment field, she would like to have worked as an assistant to a comic book writer.

The AV (adult video) companies in Japan can be divided into two groups: the "pro" companies, and the "indie" companies. The "pro" companies work with the Japan Software Morality Association, also known as "Sof-Rin", while the "indie" companies work outside of that organization. Anna Ohura debuted at age nineteen with the "pro" AV company, Crystal-Eizou on their Venus label, in the 24 February 2000 release Delicious Juicy Fruit (たわわな果実 - Tawawana Kajitsu).

Ohura's AV-acting style has been described as that of "a traditional Japanese porn star... In true Japanese fashion, Anna-chan acts demure and somewhat shy, even as she's willingly thrusting her chest out to be touched by a porn star, or opening her legs to receive cunnilingus." After several more videos with Crystal-Eizou during her debut year, she also began working for Alice Japan in December 2000. Her first video for that company, Maximum Bust, featured cosplay, S&M, and bukkake. She also made several videos with the "pro" company, TMA.

In 2002, Ohura appeared in a photo book focusing on bondage. During the shooting of this volume of photos, the photographer, "bondage master" Haruki Yukimura, suggested that he and Ohura make a video together. The result of this next Ohura/Yukimura collaboration was the September 2003 DVD, Secret Feelings, which Yukimura directed. Ohura and Yukimura would team up for another bondage video, Big Tits Bondage for Cinemagic which was subsequently re-released by Cinemagic on a 2-video DVD compilation in March 2005.

According to the JList website, in these "pro" videos Ohura's "amazing body and erotic style... won her many fans around the world." As a sign of her international and mainstream fame, Ohura appeared in Taipei in 2003, where she was a highlight of an international furniture exposition.

Some critics claim that the "indie" companies, working outside the "Sof-Rin" system, create a more interesting product. Not only do they have greater freedom, but they are also able to attract the better directors and performers. Ohura's debut with the "indie" label, Wanz Factory, was in the October 2003 DVD Super Angle of Oppai. This DVD was praised by comparing it with Ohura's work for "pro" studios, which were judged, "somewhat vanilla and boring, with straight sex and little innovation on the part of the creators." In contrast, Ohura "really shines in this great new indies release."

Late September to early October 2003 marked both the release in quick succession of three videos -- Tease Fetish Angle (September 26), Secret Feelings (September 30), and Super Angle of Oppai (October 1) -- and Anna Ohura's retirement from the Adult Video industry, at 23 years of age. (The Wanz Factory's March 2004 release of Super Angle of Oppai Premium Edition added one hour of material to the original (October 2003) version, but the additional footage came from the same sessions as the material in the original version.)
